TRUCK.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed September 11, 1905. Serial No. 277,837.

T0 at whom, it may concern:

Be it known that I, IVAR L. SJos'rRoM, of Lawrence, county of Essex,State of Massachusetts, have invented an Improvement in Trucks, of whichthe following description, in connection with the accompanying drawings,is a specification, like characters on the drawings representing likeparts.

This invention relates to certain improvements in trucks, and has forits object to produce a truck which is durable and simple inconstruction and which is especially adapted for use in mills in whichit is necessary to carry cloth from one place to another before it isrolled. I accomplish these objects by providing an open-ended truckhaving flaring sides held in place by two or more rigid supports whichextend down from the upper edge of one side, beneath the bottom, andupward to the upper edge of the other side and are rigidly secured tosaid sides and bottom at frequent intervals throughout their entirelength.

In the drawings, Figure 1 is a perspective view of a truck madeaccording to my invention. Fig. 2 is a cross-sectional view on the line2 2 of Fig. 1, and Fig. 3 is an enlarged detail sectional view on theline 3 3 of Fig. 1.

As shown in the drawings, the truck is open-ended and comprises a woodenbottom a, suitably mounted on casters 1), and two wooden sides 0 and d,which extend divergently upward from the side edges of the bottom. Anysuitable or convenient form of joint may be provided between the sidesand bottom, and strengthening-cleats are preferably secured to the outersurfaces of the sides adjacent each end. A pair of U- shaped supports ee, of heavy wrought-iron, are firmly secured by 'bolts f to the outersides of the sides and bottom, said supports extending from pointsadjacent the upper edge of each side downwardly beneath the bottom. Thetwo side sections and the bottom section of each support e are straight,and the intermediate portions 6 e are bent on a curve, and the adjacentedge portions of the bottom and sides are cut away or recessed toreceive the supports, all as indicated in Fig. 3. The bolts f arepreferably arranged so that their heads engage the inner vals, so thatthe sides are firmly held against inward as well as outward movement.The supports 6 are adapted to permit the sides to yield slightly in casethey should receive a lateral strain, so that they will not sustain assevere shocks or strains as they would if held with great rigidity, andthe durability of the truck is thus greatly increased. Moreover, whenany strain is placed on one of the sides this strain is at oncecommunicated'to both supports and the bottom and the other sidethat is,the strain is distributed throughout the whole truck so that no oneportion is excessively strained, the whole truck thus being asubstantially integral structure. Obviously the greatest strain on thesupports comes on their curved bent portions e, and as these portionsare gradually curved instead of being bent at a sharp angle the strainis distributed throughout.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is v A truck comprising a trough-like bodyentirely open at its ends and consisting of a flat wooden bottom anddeep straight sides diverging upward therefrom, and external heavysemiyielding one-piece metal supports each having a central portionsecured to and extending transversely across said bottom andupward-divergingside portions secured to and extendin upward along saidsides approximately to the tops thereof, the junctions between saidcentral and side portions of the supports being bent on a long gentlecurve overlying the junctions between the bottom and sides of the body.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
